After a phone is unlocked you are free to use any network and any SIM card. You can insert and use SIM cards purchased while abroad that allow you to take advantage of better rates for calls and SMS messaging. Basic advantages are that you no longer pay roaming charges, and you can switch back and forth between carriers/networks. Other advantages like you can increased resale value of your phone,

just know that you wont get the same service with metro any unlocked phone that metro switch service over to will only have a voice plan the data plan will be forbidden there are ways to get the whole nine yards on your phone with metro but to do so is long, drawn-out and tedious. and you have to go over they're heads but then again we are crackberry addicts when i was trying to get my storm to work properly on T-Mo service i was yanking out hair, and losing sleep but with the help of my fellow crackberry junkies my storm is running perfectly so just ask around someone will help or at least point you in the right direction

It's surprising to me that more people don't know that the provider can provide an unlock code. I wonder where they think the guys who charge for the service get the unlock codes from? BBLandia? :/

Surprisingly, all providers don't actually provide unlocking codes for free. Rogers/Fido in Canada for example will NOT provide them. However Tmobile and AT&T will provide them with very limited hassles if the person calling in has an account with them.

Us Unlockers are here to fill the void that providers can't...or won't. Unlocking pricing has come down ALOT within the past year or two. Some Tmobile/AT&T users come to us not because they don't know its available for free, but because they want it done NOW, and don't feel that $10 is expensive enough to spend time calling their carriers and trying to get an unlock code from them within 1-3 days. Most unlockers provide codes within 15 min-6 hours.

Well said. We also come in handy when let's say a T-Mobile customer wants to get a Blackberry Bold 9000 (only sold by AT&T or Rogers in North America). If they call T-Mobile, they won't give him the code because they don't have it in their system and because the phone was not sold by T-Mobile, and if they call AT&T, they won't give the customer the unlock code because he doesn't have an active account with the carrier.

So these customers have no choice to go through unlockers like us or any other reputable unlcoker to get their Blackberry unlocked and ready to be used on any GSM network.
